Here's some food for thought. The following is quoting Frank Viola in Reimagining Church. pp 128-9:
"The indwelling life of Jesus Christ is the only requirement for the unity of the Spirit. And amazingly, we Christians can detect that shared Spirit whenever we meet one another. There's an instant sense of kinship that testifies that we have the same Father.
Certainly, those who have been born of the Spirit will live in a way that is consistent with this fact. Yet they may not be clear on many spiritual things. Their personality may conflict with ours. Their worship style may be distasteful to us. They may be immature and have struggles in areas that we've surpassed. They may be painfully eccentric. Their understanding of the Bible may be poverty stricken. They may make mistakes that they regret. And they just might hold to some false ideas. Yet the fact that Christ dwells in them obligates us to accept them as family members. Not only 'in word or in tongue, but in deed and in truth'(1 John 2:18 NKJV)."
What are your thoughts along these lines?
